> You can see an educational portal listing the cost of the management license at $30 here, which isn't really a complete picture, but demonstrates that we aren't talking about something they give schools for free
You need to show that those licenses were not included in the gift. And let's just assume that they're not that stupid.
> Note that this is kinda of well-hidden, but that last link cites the "total cost of ownership" of a $149 Chromebook over three years as $588, which should give you an idea the difference between the hardware they give away, and the eventual cost of everything you need to deploy the suckers.
For a budget windows laptop or tablet the hardware cost would be higher and the support cost unlikely to be lesser.
> Schools is definitely big money for Google
Schools are a tiny segment for Google that would not hurt them in the slightest to lose. The margins on low-end hardware are not exactly the stuff dreams are made of, and they really are making peanuts on ChromeOS. We can and should contrast this to Microsoft, who has been playing the "loss leader" pricing game in educational circles for far longer with far more success.
